Russo-Japanese War is nicknamed World War Zero
The Russo-Japanese War is nicknamed World War Zero – it was a clash between two world powers that foreshadowed war on an industrial scale as seen just 10 years later again. Gigantic land battles like the Battle of Mukden showed the true cost in manpower and materiel when modern armies clashed and the naval side of the war showed the strategic importance of modern navies.
